Despite having no agriculture , the Calusa managed to dominate southwest Florida for centuries . raw research advise this inventive aboriginal American civilization built “ watercourts ” to capture and store live fish , result in a bountiful nimiety of food that facilitated sociopolitical complexness and ambitious building projection .
appear around 2,000 age ago , the talkative Calusa realm of Florida stretched from what is now Tampa Bay to Ten Thousand Islands and as far eastward as Lake Okeechobee . Their Washington city , call Calos , was located near Fort Myers in a place now known as Mound Key Archaeological State Park .
Archaeologists have studied the Calusa for decades , analyzing unreal islands made from discarded shells , the remnants of former dwellings , and their impressive dredging canals . The Calusa are singular in that , unlike the Maya , Aztecs , and Inca , they never jumped onto the agriculture bandwagon . These Native Americans were strict fisher - Orion - gatherers who relied almost exclusively on resource draw from the sea .

Yet somehow the Calusa managed to fund challenging grammatical construction projection , maintain tremendous military power , and collect tributes along a meshwork that circularize out for hundred of mile . These travail would have required an copiousness of pronto useable food , leading archaeologist to wonder how these fisher cat - gatherers were able to compile so much seafood and then prevent it all from rotting in the tropical Florida heat .
Newresearchpublished in Proceedings of National Academy of Sciences provides some much - needed answer , showing how the Calusa build seaside structures , called watercourts , which they used to bewitch and stack away fish .
“ What makes the Calusa unlike is that most other societies that accomplish this level of complexity and power are mainly raise civilisation , ” explained William Marquardt , a conscientious objector - author of the study and a research worker at the Florida Museum of Natural History , in apress release . “ For a long sentence , companionship that swear on fishing , hunting and gathering were assumed to be less advanced . But our work over the retiring 35 years has shown the Calusa developed a politically complex company with advanced architecture , religious belief , a military , specialiser , recollective - distance trade and social ranking — all without being farmers . ”

Previous inquiry argued that the watercourts were used to hold Pisces , but the new newspaper is the first to furnish a comprehensive and systematic depth psychology of these structure . For the new subject , Marquardt and his fellow look for to regain out when the watercourts were fabricate , how they were progress , how they worked , and how their show coincided with other developments in the Calusa kingdom , such as the building of enormous buildings .
Two watercourts at Mound Key were psychoanalyze in the subject area , both of which flank a duct measuring around 30 meters wide ( 100 feet ) and around 600 time tenacious ( 2,000 feet ) . essence samples containing deposit were pulled from the website , while remote sensors provide a bird ’s eye view of the hummock . Other evidence , such as bits of dispose cuticle and fish off-white , were also collect and analyze .
As the new research shows , the watercourts were work up atop a introduction of oyster shells . They were more or less rectangular in anatomy , use up a space of around 3,345 square m ( 36,000 square feet ) , which is about 62 per centum the size of an American football game field .

To make the watercourts , the Calusa walled off portions of estuary , create holding pens for Pisces . These wall , which stood 1 meter ( 3 feet ) tall , were made from shell and deposit . net or gates were likely used to forbid the fish from get away . As the new evidence shows , the watercourts were not haphazardly built from middens ( i.e. piles of waste ) , but were rather carefully designed structures . Construction and maintenance of the watercourts was no soft task , requiring “ cognition of tidal systems , hydrology , and the biology of coinage , ” consort to the paper .
Trapped in large quantity , the Pisces could be held in the watercourts and then extract for processing , such as smoking and drying . Evidence collected at the website show traces of mullet , pinfish , and Clupea harangus , which are all educate species of Pisces .
That said , the watercourts did n’t allow for long - term storage of live Pisces . Core samples take from the site exhibited dark grey splotches ordered with the accumulation of constituent material . This suggest brisk sea water was n’t getting into the inclosure , apart from some splashing during high lunar time period .
“ We ca n’t know precisely how the courts knead , but our gut intuitive feeling is that depot would have been short - full term — on the purchase order of hours to a few days , not for months at a time , ” tell Michael Savarese , a atomic number 27 - author of the subject and a geologist from Florida Gulf Coast University , in the press release .
The watercourts were manufacture between 1300 CE and 1400 CE , according to radiocarbon dating of the site . This timing coincides with major upgrade to a large dwelling known as the “ menage , ” the dare nursing home of Caalus , a Calusa world-beater who live in the mid-16th one C . This structure could house as many as 2,000 people and was the probable arse of power for “ a long - lived corporate radical ” that dominated for just about 500 years , according to the paper .
Ultimately , the researchers link the construction of these watercourts with a burgeon Calusa population , which consisted of around 20,000 person , and the outgrowth of complex political systems , as the written report describes :
The creation of [ intellectual nourishment ] surpluses required overcoming considerable challenge in terms of storage and distribution of products . Mound Key is located in a subtropical mood , which surely would have have trouble for exert the excess stability and glow , particularly with animal products . We suggest that the Calusa of Mound Key were able-bodied to solve this unequaled problem in a extremely sophisticated fashion , which partly involved keeping live Pisces in watercourt reposition areas . The expression of these facilities would have belike command interconnected effort and collective buy - in from turgid segments of society .
Equipped with an abundance of food for thought , the Calusa were able-bodied to support heavy - scale Labor Department project , generous feasts , and the ascent of other important mental home which “ lead to nifty investing in complex social and political formation , ” according to the paper .
But it would n’t last . This culture was at its summit when the first Europeans begin to arrive in the New World , a ontogenesis that upturned the Calusa and many other Native American radical .

Yet , the Calusa remain a rarefied example of a refinement chance upon a eminent stage of sociopolitical complexity in the absence of agriculture . When done right , and as the Calusa demonstrated , Pisces can power an total kingdom .
